Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Great boarding. Everything was on time. Plane was a bit old and the crew could have provided better drink service.

Boarding was a little chaotic but it was a very large flight. It just wasn’t fast. And there was no noticeable difference between zones boarding.

Crew was pleasant. Aircraft was very dated and uncomfortable for our nearly 4 hour flight. We were in row 17 and they ran out of purchasable food by the time they got to us.

We were lucky enough to arrive at the right time. The staff at YYZ did our complete check in and luggage tags for us. Even made sure we knew where we were to head next and how to get there. It truly was one of the best and easiest check inside. Thanks team.

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

First time with Porter and I can say this is best airline company in Canada. Great service, free WiFi, free snack and drinks (including beer and wine). Seats were super comfy on the Embraer jet and I appreciated the folding try table too. Staff were excellent both legs of the trip.

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

First time with Porter. Amazing experience overall, will be my airline of choice in North America whenever possible. Liked the quality of food and how it was served but one suggestion- a hot meal on the longer flights, perhaps?

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10 Tips for people flying porter from Boston. The airline doesn’t have inflight entertainment No TV No WIFI. Bring your entertainment with you.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10

Wasn’t on the flight- again. Bad weather in Halifax and I was in an accident. What a poor experience to have to pay for all this flight and not be on it

I didn’t make my flight due to poor weather and I had an accident driving there. I tried to get my money back or even credit and nothing. I have an entire flight both to Florida and back that I paid for and no one will give me any money back. I know this isn’t just Porter and it’s 3rd party- however airlines should allow these companies to take money for things they don’t get. I’m so upset. Who can afford a full flight they never take?

Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Short flight so not much to rate. Surprised I had to pay for a soda.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

Flightl was good and on time. Only problem was the quality of the air in the cabin,didn’t appear to be clearing the air circulation.

They lost my baggage on my connecting flight and we’re an hour late so I nearly missed it

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

It was cold the whole flight. Luckily had Ski-Jacket with hoodie. The food was just boiled macaroni in 'ketchup'. Better bring your own BigMac. Assisted Boarding was SUPERB!

It has nothing to do with Aer Lingus and everything to do with Frankfurt airport. There eere no visual displays of the flight destination at the gate. They kept changing our gate with semi audible public announcements and eventually I was at the wrong gate and my flight departed from the other gate.

As four hour wait with no explanation as to why the delay Very unacceptable

The 6 hour delay with minimal updates was not handled well. After many complaints from most of the un-boarded passengers, food vouchers were offered. The catering strike meant there was no food or snacks on the plane. Beverage service was heavily impacted, only water or juice was available. The staff at the gate was kind enough to inform that "if you want to eat on the plane, you will need to bring it on when boarding".

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

I go am isle seat because it was half empty Food strike no food available

Flight was delayed, jeopardizing the following connections. Food was terrible. Crew was great.

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.

Great experience on this Air Canada flight. Everyone was polite and respectful, even the passengers are very polite.

My wife and I especially liked the fact that the Toronto agent went beyond expectation to allow my wife and I to sit together. There was no option for us when we booked our seats. Very thankful!

The flight attendant bumped into me repeatedly time and time again, throughout the entire flight, preventing me from getting any rest. He seemed unaware of his actions and I was very close to saying something, but I didn't because I don't believe he would have understood or altered his behaviour. It was very irritating

I didn’t like the fact that all the customs officers went to lunch so I was in line for 90 minutes due to where the staff directed me. We were told three very different reasons for why the plane was delayed. It was a crowded plane with difficult storage situations for the Carry On bags. The Air Canada airline staff were all very good and professional. I was so disappointed in my cheese and fruit box as the cheese had molded and the fruit wasn’t fresh so I couldn’t eat the majority of the food. This was the last meal I could find as the restaurants had closed when I got in to my destination. I think you could work on improving the food quality.

Try to humanize onboarding and take AI out. It's embarrassing and useless

no kiosks to check in with- it’s 2024!!! the flight was so hot and uncomfortable - not sure if that’s what caused a lady to faint during the flight but i was absolutely miserable.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

Terrible. This airline will cancel flights at very short notice.
